This study investigated whether affective reaction predicted by the extended self-evaluation maintenance (extended SEM) model (e.g., Beach & Tesser, 1995) would be applicable to close relationships with same-sex friends. Participants (N=232) recalled or imagined eight SEM situations (defined by crossing high and low self-relevance with high and low partner-relevance with whether self outperforms partner or partner outperforms self) with close friend (N=81), romantic partner (N=98), and acquaintance (N=53). They then reported affective reactions to these occasions. As a result, the pattern of sympathy reaction to the partner predicted by the extended SEM model in the high self-relevance domain was shown to close friend and romantic partner. For acquaintance, contrary to the prediction, the pattern of affective reactions predicted by the extended SEM model was shown, regardless of the self-relevance domain. These findings were discussed in terms of the basic assumption of the (original) SEM model and the tendency of Japanese students to think of a relationship even with an acquaintance as very important.
